The pack adds a brand new co-op arcade mode (read: Horde), pitting up to four players against increasingly difficult waves of enemies. There will also be a new multiplayer mode; Capture the Orb, a "new take" on the classic CTF mode, for up to sixteen players. This mode will be accessible completely in both the trial and free versions of the DLC. The pack will also include updates to vehicles and weapons, details of which have yet to be announced.
